Instead of getting an error page I would like to get error codes only (e.g. 404) for a Web Application in IIS. How can I disable error pages on a Web Application level?

I have copied a running site to my local machine, and set it up with IIS.
For some reason when I try to access the site have setup in IIS I get an
Not Found
HTTP Error 404. The requested resource is not found.
None of the logs shows an actual error that I can use?
What sort of debug options do I have with an page that is hosted in IIS.
AppData/logs does not seem to give me any indications on why this is the case?
this is regardless whether I access it as http or https.
I have .NET Core based backend application (Swagger API) deployed in Azure App Services at https://myapi.azurewebsites.net
It works fine except of one method where I invoke a redirection to another website via GET request in browser as following:
https://myapi.azurewebsites.net/api/Method/Ext&RedirectUrl=https://externalsite.com
The link above shows Error 404 Not Found in a browser and I see that one "/" is missing from the RedirectUrl in IIS logs so this must be the reason:
GET /api/Method/Ext&RedirectUrl=https:/externalsite.com
The IIS error code is the same - 404.
There is no Application Gateway or anything else that can modify the URL.
I checked my App Services instance configuration and did not find any settings that could modify the URL.
Did anyone experience the same issue?
I recently uploaded my web application in iis, but I have the error that when I update the web application it gives me a 404 error, I can use it without problem it is only when I update.
Have you checked the IIS Admin Service?
Please check the solution here: link
We have moved our website from local environment to Azure. But we are getting different error message for error code 404. Below are screen shots.
In case of existing website.

If you are receiving a 404 error while accessing your custom domain, then you are most likely missing the link between your Azure App Service Web App configuration and your custom domain.

I am at a loss as to how to present a custom error page, with professional branding, for errors covering:
403 - Wep App stopped - currently get blue page with Azure text.
503 - Service Unavailable - currently get white page with "service unavailable"
I have tried to use CloudFlare custom error pages, but this does not work. For a 403, traffic still gets routed throught to Azure, where it gets the standard Azure 403 Page.
Must be possible?
There are two categories of HTTP errors that can happen on Azure Web Apps:
Those that happen in IIS on the Web Worker where your site is running.
Those that happen before it reaches that. This includes cases when the site is stopped, in the process of restarting, or potentially affected by some other issue in the system.
One way to tell if an error is #1 or #2 is to turn on http logging, and see if it gets logged. Only #1 will.
For #1, you can customize errors using standard techniques. But for #2, there is currently no way for you do customize the pages returned by Azure.
